Okay, you know
platinum is one of the most popular metals used to make high-end jewelry
products, but did you know:

1.Platinum is 35% rarer than gold – More than 1,700 tons of gold are mined
annually; compare that to only 130+ tons of Platinum. Platinum and gold are
both very rare because they both come to earth from space rocks; they have
never been, and never will be formed on Earth because they‘re physical
properties won’t allow it. Any element that is heavier than iron is typically
formed when a star becomes a supernova. You could literally fit all of the platinum
ever mined on Earth into an average-sized living room.

2.Platinum has one of the highest melting points – it melts at 3,215 degrees. For this reason it
is commonly used to make crucibles and other lab equipment.

3.The platinum you buy is rarely pure – it’s not very strong so it’s commonly alloyed
with other metals like palladium, ruthenium, and iridium. Unless you’re buying
platinum for investment purposes it is probably not pure.

5.Platinum is the heaviest precious metal – A single cubic foot of it weighs a bit more
than 1,330 pounds – so even if you were an Olympic bodybuilder, you’d be able
to fit your arms around it easily, but lifting it more than a few inches would
still be nearly impossible.

6.Most platinum comes from 2 countries – South Africa and Russia supply 90% of the
world’s platinum, and almost all of the platinum mined in South Africa is used
to fulfill industrial needs. That means almost all platinum used for jewelry
comes from Russia.

7.Platinum was once only legal for industrial
uses – during World War II the
U.S. government declared it a strategic metal and temporarily banned its use in
jewelry and all other non-industrial
applications, so no one was allowed to buy or sell platinum unless it was going to be used for an
approved purpose.

8.It can’t be scratched(technically)
– alright that’s kind of a half-truth. Platinum CAN be scratched, but unlike
Gold and Silver it will not lose any mass when it is scratched (if it is pure).
In other words, the metal will simply be dented inwards, not scraped off the
surface.

9.It is a diamond’s best friend – Platinum is used to secure all of the world’s
most famous diamonds, including the Jonker I, the Koh-I-Noor, and the
world-renowned Hope diamond.

10.It is absurdly difficult to mine and refine – it takes a starting supply of ten tons of
ore and a five-month refining process just to produce one ounce of top-grade
platinum bullion.
